Before proceeding with the installa on of the equip-ment agree the loca on with the client, taking into ac-count the following points:1. The base must be able to support the weight of the

unit,2. The safe distances between the unit and other

equipment or structures must be strictly respected to ensure the intake and outlet air is free to circu-late,

3. The equipment must be installed by a competent and qualifi ed technician, in compliance with the applicable na onal legisla on of the country of des na on, respec ng the required minimum maintenance access spaces.

3. POSITIONING

• Before lifting the unit verify the lifting capability of the equipment being used, taking into account the information provided with the packaging.

• When lifting insert through the unit's base holes lifting bars (NOT PROVIDED) of sufficient length to locate the lifting chains and safety lugs.

• Position the unit in the place indicated by the cli-ent, inserting between the unit's base and the base support a rubber pad (minimum 10 mm thick) or anti-vibration mounts. For further infor-mation refer to the dimensional tables.

• Secure the unit and ensure it is level; check that sufficient access is provided for hydraulic and elec-trical connections.

• In the case of installation where gusts of wind may occur adequately secure the unit using appropri-ate ties.

WARNING:If the unit is installed in particularly windy locations the provision of wind barriers may be necessary to avoid malfunctions.

ATTENTION:lifting bars are NOT provided.

WARNINGThe selection and installation of components external to the unit are the responsibility of the installer and must be carried out in accordance with good working practices and applicable standards of the country of destination.

WARNINGThe hydraulic piping to the unit must be adequately sized for the required flow rate. The water flow rate through the heat exchanger must always be constant.

WARNINGCarefully clean the system prior to connection to the unit. This clean-ing eliminates welding slag, dirt, rust or any other impurities from the piping. These impurities may otherwise be deposited within the unit and cause a malfunction The connecting piping must be adequately supported so as not to impose any weight onto the unit.

WARNINGSYSTEM DRAININGDuring the winter period the water in the heat exchanger may freeze when the system is off, causing irreversible damage to the heat exchanger.There are three solutions to avoid the risk of freezing:1. Complete draining of water

from the unit.2. Operating with glycol, with

a percentage of glycol se-lected in accordance with the minimum anticipated external temperature.

3. Use of electric heaters. In such cases the electric heat-ers must always have power available for the whole period of possible freezing (unit in stand-by).

8. CHECKS AND FIRST START UP

8.1. PREPARING FOR FIRST START UP

It is reminded that for units of this series, if requested by the Aermec client or the legal owner and only on ITALIAN territory, free start-up is provided by the regional Aermec technical service assistance. The start-up must be previously agreed based on the intended me of comple on of installa on. Before the start-up all the works (electrical and hydraulic connec- ons, fi lling and ven ng of air in the system) must be

completed.

8.2. START UP

8.2.1. PRELIMINARY CHECKS BEFORE POWERING UP

Check:1. All safety precau ons have been followed.2. The unit has been appropriately fi xed to the

support base.3. Minimum clearance spaces have been ob-

served.4. Power supply cables are correctly sized and ca-

pable of suppor ng the electrical requirements of the unit (see sec on on electrical data) and that the unit is correctly earthed.

5. All electrical connec ons are correctly termi-nated and ghtened.

8.2.2. CHECKS TO BE DONE WHEN POWERED UP

1. Apply power to the unit by turning the main iso-lator to the ON position. The display will power up after several seconds after applying power, check that the operating status is on OFF (OFF BY KEYB on the lower part of the display).

2. Check with a tester that the power supply volt-ages on the phases U-V-W are 400V ±10%, check that the phase imbalance is not greater than 3%.

3. Check that the connections made by the installer comply with the documentation.

4. Check that the compressor crank case heater(s) are operating by measuring the increase of oil sump temperature. The heater(s) must be in operation for at least 24 hours before starting the compressor, and in all cases the sump oil temperature must be 10-15 K above ambient temperature.

HYDRAULIC CIRCUIT

1. Check that all hydraulic connections have been correctly installed, that the instructions on the labels have been followed, and that a mechani-

cal filter has been installed on the inlet to the evaporator. (Mandatory component otherwise the warranty will be voided).

2. Confirm that the pump(s) are operating and that the flow rate is sufficient to make the contact on the flow switch.

3. Check the water flow rate by measuring the differential pressure across the evaporator inlet and outlet and calculating the flow from the evaporator pressure drop diagram provided in the documentation.

4. Check the correct functioning of any flow switch installed; close the isolating valve on the evaporator outlet and observe the result on the unit display panel; open the valve and reset the flow trip alarm.

8.3. FIRST START UP

After having rigorously followed the above checks it is possible to start the unit:1. Close the electrical panel.2. Turn the main isolator to ON.3. Press the key ON for 3 seconds to start the

unit. Pressing the key ON displays the water temperature and the operating mode of the unit. Check the operating setpoint parameters and reset any alarms present . After a few minutes the unit will start.

8.3.1. CHECKS WITH THE UNIT RUNNING

REFRIGERANT CIRCUIT Check:- That the compressor input current of the compres-

sors is less than that indicated in the table of electri-cal data.

- That in three phase models the compressor noise is not abnormal, indicating a reverse rotation. In this case reverse one of the phases.

- That the voltage values are within the determined limits and that the phase imbalance (three phase power) is less than 3%.

- Presence of any refrigerant leaks, in par cular from connec ons to gauges, pressure transducers and pressostats. (Vibra ons during transporta on may have loosened connec ons).

- Superheat Compare the compressor suction temperature with

a contact temperature sensor reading with the temperature of the low pressure gauge (saturated suction temperature corresponding to the evaporat-ing pressure). The difference between these two temperatures is the superheat value. The optimal values are between 4 and 8 K.

- Discharge temperature If the values of sub-cooling and superheat are normal the temperature measured in the discharge line from the compressor must be 30/40 K above the condensing temperature.

SAFETY AND CONTROL DEVICES

Check:- The manual high pressure pressostat, which stops

the compressor and generates and alarm when the discharge pressure exceeds the preset value. The correct operation is checked by closing the refriger-ant isolating valve to the heat exchanger (in cooling

mode) and keeping a check on the high pressure gauge, verify the operation corresponds to the rated value. Warning: in the event the pressostat does not operate at the rated value immediately stop the compressor and investigate the cause. Reset is manual but can only be done when the pressure drops below the differential setting. (For the values of the trip and differential setting refer to the tech-nical manual).

- Anti-freeze protection The electronic control of the anti-freeze protection

is from the water temperature sensor leaving the evaporator prevents freezing of water when the temperature is too low. The operation of the anti-freeze protection can be checked by increasing the setpoint value until it is above the temperature of leaving water and checking the water temperature with a high precision sensor. Confirm that the unit stops and generates the responding alarm. After this check reset the anti-freeze setpoint to the original value.

9.2. COMPRESSOR DELAY TIMERS

To avoid excessive compressor starts two func ons are provided.

- Minimum time compressor is OFF 180 seconds.- Minimum time compressor is ON 120 seconds.

9.3. CIRCULATING PUMPS

The wiring schema c provides outputs to control the circula ng pumps. The system pump starts immediate-ly and a er 40 seconds of opera on, when the water fl ow is stabilised, the pressure diff eren al/fl ow switch control func on is enabled. If no alarms are present the unit will start.

9.4. ANTI FREEZE ALARM

The alarm 11 is always ac ve even in standby mode. To prevent damage to the plate heat exchanger by freezing of the water within the unit is stopped and an alarm raised if the water temperature drops below the minimum an -freeze setpoint of 3°C. The unit can only re-start a er a manual reset and if the an -freeze sensor reads a water temperature above 4°C 12. With the unit in off mode and with a water temperature below 4°C the factory fi ed electric heaters on the heat exchanger are turned on, and turned off when the water temperature exceeds 5°C. The water pump always remains ac ve.

9.5. WATER FLOW ALARM

The unit has a low water fl ow rate alarm using a fac-tory fi ed diff eren al pressure switch or fl ow switch.

This safety ac vates a er the fi rst 40 seconds of pump opera on if the water fl ow rate is not suffi cient. The opera on of this alarm stops the compressors and the pump.
